Create custom hacth pattern
by romeo AKARA Dec. 26, 2021

Dec. 26, 2021

Hello,I am trying to create hatch patterns corresponding to the attached image. I am using the following example: https://stackoverflow.com/questions/17285154/how-to-fill-a-polygon-with-a-c…. Here is an excerpt of my script:hatch_path =Polygon([[0,0], [0, 0.1], [0.1, 0.1], [0.1, 0.2], [0.2, 0.2], [0.2, 0.1],[0.3, 0.1],[0.3, 0],[0.2, 0],[0.2, -0.1],[0.1, -0.1],[0.1, 0]], closed=True, fill=False).get_path() The result is not quite what I want. I will appreciate if someone can point me to how best solve this issue. Thanks,Romeo

mplcairo crashes python3.10
by Neal Becker Dec. 7, 2021

Dec. 7, 2021

I'm using Fedora 35, with python3.10 mplcairo is python3-mplcairo-0.4-3.fc35.x86_64, but I've also tried pip install mplcairo and get the same result. In matplotlibrc I have backend: module://mplcairo.qt Any simple plot to the screen results in: ------------------- In [2]: Traceback (most recent call last): File "/usr/lib64/python3.10/site-packages/mplcairo/qt.py", line 36, in paintEvent pixel_ratio = self.pixel_ratio AttributeError: 'FigureCanvasQTCairo' object has no attribute 'pixel_ratio' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib64/python3.10/site-packages/mplcairo/qt.py", line 38, in paintEvent pixel_ratio = self._dpi_ratio AttributeError: 'FigureCanvasQTCairo' object has no attribute '_dpi_ratio' --------------- I had been using this same setup for quite some time, but perhaps it's the update to Fedora34 that is now triggering the issue. Any ideas? I've already adapted many of my scripts to use mplcairo.multipage so need this to work again. Thanks, Neal -- Those who don't understand recursion are doomed to repeat it

Re: [Matplotlib-users] mplcairo on fedora 35
by Neal Becker Dec. 7, 2021

I tried installing latest mplcairo from github, and the problem is gone. So the issue seems to be the current mplcairo release version is not compatible with fedora 35, either python3.10 or some qt (or pythonqt) version issue. -- Those who don't understand recursion are doomed to repeat it

deprecation of mpl_toolkits' colorbar implementation - substitute?
by Slavin, Jonathan Dec. 3, 2021

Dec. 3, 2021

Hi, I'm wanting to do something like in the example "Demo Axes Grid", the 2nd case where the grid has a single colorbar. That works the way I want it, but I get a deprecation warning: MatplotlibDeprecationWarning: Since 3.2, mpl_toolkits's own colorbar implementation is deprecated; it will be removed two minor releases later. Set the 'mpl_toolkits.legacy_colorbar' rcParam to False to use Matplotlib's default colorbar implementation and suppress this deprecation warning. So, I understand that that warning can be suppressed, but I'd rather find a non-deprecated way of doing the same thing. So far I haven't found it. The particular command that results in the warning is: grid.cbar_axes[0].colorbar(image) I don't know of a way to add a colorbar to the grid of images the way I want it. Any help would be appreciated. Thanks, Jon -- Jonathan D.
